An data packet network telephony system provides identification information of
an end user terminal making an Internet telephone call to a call center terminal
and provides a call center agent with the ability to cause an end user terminal
making an Internet telephone call to display selected web pages and or to synchronize
displays between the agent and end user terminals. In one embodiment, customer
identification information is provided in-band. In another embodiment, customer
identification information is accomplished out of band, in some cases using an
identifier of the PSTN gateway as an index into a table to identify an end user
terminal. In another embodiment, an agent may enter DTMF (dual tone multi-frequency
tones) to push web pages to an end user terminal. In still other embodiments, a
second communications link between the end user terminal and the agent's terminal
is established, allowing for data sharing/synchronization.
